Two ligands, a and b, both form complexes with a particular metal ion. when the metal ion complexes with ligand a, the resulting

solution is red. when the metal ion complexes with ligand b, the resulting solution is yellow. which of the two ligands produces the larger δ? two ligands, and , both form complexes with a particular metal ion. when the metal ion complexes with ligand , the resulting solution is red. when the metal ion complexes with ligand , the resulting solution is yellow. which of the two ligands produces the larger ? ligand a produces a higher δ ligand b produces a higher δ ligands a and b produce the same δ there is not enough data to determine.

Answer:

The equilibrium constant is $K_c= 2.8*10^{-4}$

Explanation:

From the question we are told that

The chemical reaction equation is

$Fe_{2} O_{3}_{(s)} + 3H_{2}_{(g)} -----> 2Fe_{(s)} + 3H_{2} O_{(g)}$

The voume of the misture is $V_m = 5.4L$

The molar mass of $Fe_{2} O_{3}_{(s)}$ is a constant with value of $M_{Fe_{2} O_{3}_{(s)} } = 160g/mol$

The molar mass of $H_{2}_{(g)}$ is a constant with value of $H_2 = 2g/mol$

The molar mass of $H_{2}O$ is a constant with value of $H_2O = 18g/mol$

Generally the number of moles is mathematically given as

$No \ of \ moles \ = \frac{mass}{molar\ mass}$

For $Fe_{2} O_{3}_{(s)}$

$No \ of\ moles = \frac{3.54}{160}$

$= 0.022125 \ mols$

For $H_{2}$

$No \ of\ moles = \frac{3.63}{2}$

$= 1.815 \ mols$

For $H_{2}O$

$No \ of\ moles = \frac{2.13}{18}$

$= 0.12 \ mols$

Generally the concentration of a compound is mathematicallyrepresented as

$Concentration = \frac{No \ of \ moles }{Volume }$

For $Fe_{2} O_{3}_{(s)}$

$Concentration[Fe_2 O_3] = \frac{0.222125}{5.4}$

$= 4.10*10^{-3}M$

For $H_{2}$

$Concentration[H_2] = \frac{1.815}{5.4}$

$= 0.336M$

For $H_{2}O$

$Concentration [H_2O] = \frac{0.12}{5.4}$

$= 0.022M$

The equilibrium constant is mathematically represented as

$K_c = \frac{[concentration \ of \ product]}{[concentration \ of \ reactant ]}$

Considering $H_2O \ for \ product$

And $H_2 \ for \ reactant$

At equilibrium the

$K_c = \frac{0.022}{0.336}$

$K_c= 2.8*10^{-4}$

It is possible for a particular element to have various numbers of neutrons. True False

umka2103 [35]

Answer:

<em><u>True</u></em>

Explanation:

Every element is constituted by atoms with the same atomic number, which is the number of protons in their nuclei. So, all the atoms of a same element have the same number of protons.

For instance, the element sodium has atomic number 11, and all its atoms have 11 protons.

The atomic number identifies uniquely every element.

In the atomic nuclei there are protons and neutrons. Neutrons can vary from one atom of a particular element to another atom of the same element. That is what the term isotope accounts for. Isotopes are atoms with the same atomic number and different number of neutrons.

Most elements have different isotopes. The atomic mass of fifferent isotopes of a particular element will differ among them, because the neutrons account for the mass.
